The PR maven, 37, was photographed exiting her Bondi home Friday morning sans wedding or engagement ring. She hired a private jet to take her and the couple's children Pixie, 5, and Hunter, 3, from Sydney to Cooma, where Oliver was released this morning after serving a one-year sentence for insider trading.

The 31-year-old banker exited Cooma Correctional Centre, hopped into a black Range Rover, and was taken to Cooma airport where he greeted Pixie with a big hug at the top of the jet's staircase.

Roxy had previously told the children that their father was away in China on a business trip during his sentence.

"My children think he's coming home from work and that's how it needs to remain. If there was some big gala affair that would seem out of character," she told Daily Mail in April.

"It'll be business as usual. He'll be released on the 23rd of June and the most important thing for him will be to spend as much time as he can reconnecting with the kids."

The socialite has frequently alternated between wearing her diamond engagement ring and a series of other diamond baubles on her ring finger over the past few months, but in the past few weeks she has increasingly opted to go bare-handed.
